After Representatives Joe Barton (R-Texas) and Edward J. Markey (D-Mass.) sent a letter to Steve Jobs asking to explain iAd tracking, Apple's general counsel, Bruce Sewell, responded with a hand delivered letter. The original letter was sparked by Apple's location-tracking wording in the recent iTunes update.

Apparently we may not see iOS 4 for the iPad until November. This comes out from a report that's outlining advertisers' plans for Apple's iAd program which is pointing to signs that the new ads won't market to iPad users until iOS 4 becomes available for it in November.

As Apple’s Worldwide Developer Conference winds down Friday, the company has kicked off two new programs for their developers. First up, the doors have swung open for those wishing to join the iAd network. The Safari Developer Program is also ready to accept developers as well.

The moniker doesn't exactly roll off the tongue, but Apple's iAd will
bring a new face to mobile advertising and a new way for developers to
make money off of their applications. iAd will pair "motion plus
interactivity" in in-app advertising. iAd will include interactive and
video content that will not take users out of the app they're using at
the moment.
